security concept. Siemens' products and solutions constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit (https://www.siemens.com/industrialsecurity).
Siemens' products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are

Potential distributor modules 6
6.1 Introduction
Properties of potential distributor modules

A potential distributor module (PotDis module) consists of a potential distributor BaseUnit
(PotDis-BU) and a potential distributor terminal block (PotDis-TB) installed on top of it.
A system-integrated potential distribution is possible with the various PotDis-BUs and
PotDis-TBs.
You can place potential distributor modules at any location with the ET 200SP distributed I/O
system. In doing so, you must observe the same design rules that apply to the design of a
potential group from the BaseUnits for I/O modules. The following information is particularly
important:
● The potential groups opened with a light-colored PotDis-BU must contain no I/O modules.
You can integrate any dark-colored PotDis-BUs into I/O module potential groups provided
these are based on SELV/PELV supply.
● If you do not need the additional terminals of the PotDis-TB in a potential distributor
module, replace the PotDis-TB with a BU-Cover.
● You may only connect one potential group within a combination of PotDis-BU and PotDis-
TB.
● Only SELV/PELV potentials are permitted on PotDis-BUs. Separate different SELV/PELV
potential groups using light-colored PotDis-BUs.
● With potential distributor modules you may only connect to the PotDis-TB versions BR-W
and n.c.-G potential, which exceed the voltage level of SELV/PELV.
● PotDis terminals are not directly configurable as PotDis via GSD/GSDML. When
configuring with GSD, always use an empty module; with GSDML, integrate a free space.
Potential distributor modules are configurable with STEP 7/STEP 7 TIA Portal. Individual
versions are listed in the following table:
Engineering with version/HSP

STEP 7 TIA Portal
• Configurable as of version HSP0241 up to V13 SP1 Update 8
HSP0241 up to V14
• Configurable as of version
HSP0241 up to V14 SP1 Update 5
• Configurable as of version HSP0241 up to V15 Update 1
• Configurable as of version
STEP 7
• Configurable as of version HSP0293 up to V5.5 SP4
